Can you use the non ash:: variants all the time? I believe both end up in the
same place and if we can it would be good to nuke the ifdefs (and the ash
include above).

Done. (I didn't remove the ash::wm:: implementations entirely here because
there's a few other uses of them, and this will need to be merged back to 49.)

   return ash::wm::IsActiveWindow(window);
 #else
-  NOTIMPLEMENTED();
-  return false;
+  return wm::IsActiveWindow(window);
 #endif
 }
